serializers.py

class UploadSerializer(UploadBaseSerializer):
    IMG_TYPE = ['gif', 'png', 'jpg', 'jpeg', 'webp']
    LOG_TYPE = ['txt', 'log', 'zip', 'gz']
    MP4_TYPE = ['mp4']
    UPLOAD_TYPE = IMG_TYPE + LOG_TYPE + MP4_TYPE

    file = serializers.ListField(
        child=serializers.FileField(
            required=True, help_text='上传文件',
            validators=[
                FileExtensionValidator(
                    UPLOAD_TYPE
                )
            ]
        )
    )

    def validate(self, attrs):
        logger.debug("attrs:{}".format(attrs))
        file_list = attrs.get('file')
        if not file_list:
            raise ValidationError(detail={
                'file': _('file is None')
            })
        if len(file_list) == 1:
            # 单文件
            file_url = self.save_file(file_list[0])
            attrs['data'] = file_url
            return attrs

        # 文件数组
        url_list = []
        for file in file_list:
            file_url = self.save_file(file)
            url_list.append(file_url)
        attrs['data'] = url_list
        return attrs
